Formation of DNA adducts and of water-soluble metabolites was studied in monocytes of 86 first-degree relatives of 15 families. Tests were performed with blood monocytes using (G-3H)-benzo[a]pyrene as a model pro-carcinogen. Variance analysis revealed significantly higher inter-familial than intra-familial variations. From these data we conclude that the formation of DNA adducts is genetically controlled. Therefore the enhanced formation of benzo[a]pyrene DNA adducts in lung cancer patients found in earlier studies may reflect a genetic predisposition for lung cancer in some patients.

D004198 Disease Susceptibility A constitution or condition of the body which makes the tissues react in special ways to certain extrinsic stimuli and thus tends to make the individual more than usually susceptible to certain diseases.

D004247 DNA A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).
